I have this problem with my PC where sometimes (but not always), after waking up from sleep- or slumber modus, the screen resolution is reset to something like 1024 x 728 instead of the usual 3440 x 1440. In those cases, I cannot manually reset the resolution (no other resolutions are visible in the settings), so I have to restart the PC. This always fixes the problem, but is also quite annoying ( I have to close and restart all applications…)
Does anyone know what might cause this, and how I fix it? It improved for a bit after I changed the thermal paste on my video card, but recently it became a regularly occurring problem again…
Screen: LG Ultrawide, drivers are up to date
PC: Intel(R) Core™ i7-9700K CPU @ 3.60GHz 3.60 GHz, AMD RADEON RX 590 8GB videocard. Again: drivers are up to date.
Thanks in advance for any suggestions!
